Hi Carl we have a 98 minibus in the yard and it wont do any more than 70 flat out i think thats the way most of the smiley fronts are(except for the odd one) when they get to this stage of their life as for mpg never checked it but wouldnt be suprised if ours wasnt doing any more. If it has as many miles as ours (210,000) i wouldnt try to tune it it will more than likely blow up although they are a hardy old engine
